SPECIFICATION forming part of Letters Patent No: 549,951, dated November19, 1895.

Application filed June 17, 1895. Serial No. 553,022. (No model.)

T a/ZZ whom/ zit may concern,.-

Be it known that I, THOPHILE BLANGER, a citizen of Canada, residing atMontreal, in the district of Montreal, in the Province of Quebec,Canada, have invented certain new and useful Improvements in Padlocks;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part hereof.

The object of my invention is a padlock specially designed forcar-doors, mail-bags, and the like, and one that cannot be openedwithout punching a card or ticket which has been inserted prior to thepadlock being locked. This card is fastened in the lock and cannot bewithdrawn until the key is turned.

In the drawings, Figure 1 is a perspective view of my lock. Fig. 2 is afront view, the cover being removed, showing it locked, the dotted linesshowing it unlocked and the position of the key when the cardV or ticketis being pushed out. Fig. 3 is a section on line 3 3, Fig. 2. Fig. 4 isa section on line 4 4, Figs. l and 2, showing the card inserted andlocked. Fig. 5 is a similar section unlocked and the card partlywithdrawn. Fig. 6 is a section showing the interior of the lock from theback, the key-bit being shown engaging the bolt of the lock and also indotted lines engaging the device for pushing out the card or ticket.Figs. 7, 8, and 9 are details of the lock. Figs. 10 and ll are an endview and section of the key.

The lock-casing, which I prefer to make rectangular in shape, consistsof the back A, side walls and 2l, top wall 22, bottom 23, and cover B.The back, side, top, and bottom walls may be cast integrally. Lugs 24and 25 are formed at each side of the top on the back and cover, and inthe lugs 25 the curved jaw C is pivoted. The free end of the jaw isslotted at c for the locking-bolt to pass through. An aperture 26 ismade in the top wall 22 for the passage of the end of the jaw. Studs 27and screw 28 are provided for holding the cover in place. A key-post Dis secured in the back and projects into the keyhole in the cover. Thispost is cut away at CZ for the passage of a card or ticket to behereinafter mentioned.

The cover B is provided with apertures fitting the studs 27 and screw28, a keyhole 29, and a slot h, through which any number or legend onthe card or ticket may be read. A guard or keeper E is pivoted to thecover, so as to cover the keyhole 29 and slot h.

F is the lock-bolt adapted to be shot by the spiral spring f. A slot 30is provided in the center of the bolt and the bolt slides on a flattenedstud 31, the said stud passing through the said slot 30. The front end32 of the bolt is thinner than the rest and is adapted to enter the slotc in the end of the jaw C, the upper portion of the end 32 being rounded01T, so that the bolt will be pushed in against the spring fwhen the jawis pressed down. A tongue 33, turned back and depending from the bolt F,is formed integrally therewith and adapted to be engaged by a key-bit lcof the key K, and'thus retract the bolt and disengage it from the slot cin the jaw C.

Thus far I have described a simple and efficient padlock, and below isadescription of a device which prevents the lock from being tamperedwith.

A slot 34 is formed in the side wall 20 of the case. This slot is justwide enough to admit a card or ticket T. This ticket or card T is pushedin through the said slot 34 and rests upon a plate 35 in the lowerportion of the casing, the said plate 35 being just far enough from thecover B to admit the card or ticket snugly. The cut-away portion d ofthe keypost D forms a guide for one side of the card, a raised portion36 on the plate 35 forms a guide for the other side, and a sliding bar37 forms a stop for the end of the card.

The plate 35 is cut away at 38 to miss the key-post D and allow the keyK to be inserted. Two longitudinal slots 39 are formed near the end ofthe plate 35 to allow rivets 40 to secure the sliding bar 37 to aplate4l,this plate being pressed away from the side wall 20 by a spring 42'7and is provided with a notch 43, adapted to be engaged by the key-bitlo, as shown in Fig. 6. A guide for the mechanism for closing the slot34 is formed by depending wall 44, formed integrally with the plate 35and the side wall 20 of the casing. This depending wall reaches to theback A and forms a support for the plate 35 and also an abutment for thespring 42.

The slot 34, through which the card or IOO down the bolt 5l.

ticket is inserted, is closed by the following device, viz: A slidingplate 45, the full length of the slot 34 and sliding against the wall 2Oof the casing and between it and the depend ing wall 44, is heldinposition by a pin 46, secured in the said side wall 20 and passingthrough a slightly elongated slot 47 in the said plate. A recess 48 isformed in the cover B to receive the edge of the plate when the slot34is closed. The under side of this plate, which is thicker than theupper portion, is provided with a series of inclined faces 49, adaptedto be engaged by a series of similar inclined faces 50 of a bolt 51,sliding under the said plate or between it and the back A of the casing.A spring 52 presses this bolt toward the top of the casing. A stop 52 isprovided abutting against one of the studs 27. The bolt is then bentaway from the side wall 20, so that the upper end comes in contact withthe nose of the curved jaw C.

The key I( has one-half of the barrel formed with a knife-edge 54,adapted to eut olli' that portion of the card or ticket T resting on theportion d of thekey-post l). A slot 55 is made at the upper end of thebarrel for the extraction of the bits of cardboard thus cut off.

An eye G is formed on the lower end ofthe lock-case, by means of whichthe lock maybe secured to the door or bag to prevent its be ing lostwhen not in use.

The operation of the device is as follows: A card or ticket is insertedin the slot 34 and numbers or legend or word written or printed so as toappear at the slot 7L in the cover. The back is then placed in positionand jaw C pressed down. The nose of the jaw presses The inclined faceson this bolt, engaging the inclined faces on the plate 45, press theplate up so as to cover the slot 34. At the same time this is being donethe nose of the ,jaw presses back the bolt F until end 32 is oppositethe slot c, when the spring-slot, the bolt, and the jaw are locked. Inunlocking the lock it will be seen that a key cannot be inserted withoutmutilating the card or ticket T, thus enabling any one to see at aglance if the lock has been tampered with. The right key K on beinginserted cuts off a selnicircular piece from the card, and then, onbeing turned in the direction of the arrow, engages the tongue on thebolt F and retracts it. The bolt 51 is then pressed up by the spring 52,and so allows the plate 45 to drop, opening the slot 34. The key is thenturned until the position shown by dotted lines in Fig. 6 is reached,when it engages the notch 43, and, continuing, draws the sliding bar 37toward the slot 34, and so pushes the edge of the card or ticket Tthrough the said slot 34 and enables it to be withdrawn. The back ishermetically sealed when locked, the guard or keeper closing the keyholeand slot h, the end of the jaw C, the slot in the top wall oi' thecasing, the sliding plate, and the s101534, so that it is impossible forwater or dust to enter.

Having now fully described my invention, what I claim isl. In apad-lock, the combination with the casin g having a slot for theinsertion of a card or ticket oi' a sliding plate adapted to close thesaid opening, a series of inclined :li'aces on the under side of thesaid plate, a bolt having a series of inclined faces adapted to engagethe said inclined faces on the sliding plate, the said bolt by beingpushed one way will cause the sliding plate to close the opening and theother way will open Ait substantially as set forth.

2. In a paddock, the combination with a sliding plate adapted to close aslot in the side of the casing, inclined faces on the under side of thesaid plate, a bolt having a series of inclined faces adapted to engagethc inclined faces on the said. plate, a spring pressing the said boltin one direction, and the jaw of the lock, the nose of which is adaptedwhen the lock is being closed, to press the said bolt against the saidspring su bstaniiall y as set forth.

3. In a pad-lock, the combination with the casing having a slot in theside for the inscrtion of a card or ticket and means for openingorclosing the said slot, of a plate on which the ticket is pushed, asliding bar sliding on the said plate, the said bar being connected byrivets passing through slots in the said plate to a sliding plate on theother side thereof a spring adapted to push the said sliding plate awayfrom the said. slot, the said sliding plate having a notch adapted to beengaged by the bit of the key, substantially as set forth.

4. In a pad-lock the combination with the key post D having a cut awayportion d, on which the edge of a ticket or card rests, of the key Khaving a knife edge 54 formed on the barrel adapted to cut oii thatportion of the ticket or card resting on the said cutaway portion (l anda slot 55 through which the portion of the ticket cut off may beextracted from the barrel of the key, substantially as set forth.
